Abstract (en)
1. Thermostatic valve (10, 22) arranged in a heating circulation comprising a control device (36) for a programmable actuation of the valve (12, 16) by providing an increased temperature for the temperature sensor (24) of the valve (12, 16), whereat the increased temperature is taken from the heating circulation and the control device (36) merely switches the transfer of the increased temperature to the temperature sensor, and further comprising a branch circuit (32) connected to the heating circulation and being in heat exchange with the temperature sensor (24) of the valve (12, 16), characterized in that a pilot valve (34) is provided in the branch circuit (32) and is switched by the control device (36) to open or block, respectively, the throughput of the heating fluid through the branch circuit and that the branch circuit (32) is connected to the heating circulation downstream and upstream of the valve seat (12) to form a bypass with respect to said valve seat (12).
Abstract (de)
Es wird ein durch eine programmierbare Steuerung abschaltbares Thermostatventil angegeben, das die Energie für die Abschaltung dem Heizungskreislauf entnimmt. Insbesondere ist eine Abzweigleitung (32) vor und hinter dem Ventil (12/16) an den Heizungskreislauf angeschlossen und eine dem Ventil zugeordnete Steuerung steuert lediglich über ein Pilotventil (34) den Durchtritt des Heizmittels durch die Abzweigleitung.
